For my money, no one will ever beat Barbara Stanwyck in Double Indemnity, but the kids these days -- they're all about color photos. So, in an effort to elicit that sick knot in your stomach combined with an overpowering need to have sex with someone you shouldn't, I would like to celebrate the best adulteresses from the last 30 years, which should not be read as tacit permission to do something dirty. And wrong. As the saying goes: There's nothing more sexy than a woman who cheats, as long as she's not your wife.
